I have an NSOutline view which conceptually contains "directories" and
"files" in those directories, much like Finder's list view.
When a user selects/unselects a directory row, I would like to
select/unselect all children of that row.
I can do the selection operation in delegate method
outlineView:shouldSelectItem:. But how can I be informed when the user
UNselects such a row? I guess I could compare the values of
selectedRowIndexes before and after, but that seems like the hard way.
What's the best way to be informed of the user unselecting a row?
TIA,
-Dave
